IMPROVEMENT IN EARTH-CLOSETS.

To all whom it may concern Be it known that I, GEORGE W. ROBERTS, of Wilmington, in the county of New Castle and State of Delaware, have invented a new and improved Earth- Oloset and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompan'yinglr drawing-forming part of this specification, in which- Figure l represents a front view of said closet when closed.

Figure 2, an end view of the same.

Figure 3 is a plan or top view of the same through the top, showing the interior arrangementof working parts.

Figure t shows a front view of said. closet with doors open for use.

Figure 5 is a section thl'ough the middle of my improved cl'osetvand the parts beyond, looking into the further half on the line AA.

Figure 6 is a section through the middle of my closet and the parts beyond, on the line a a.

Figure 7 is a top view, witl1 the cover removed, showing interior of hopper and the valve beyond.

My invention relates to that class of closets in which earth is used to absorb odor from the exorement by being mixed with it, deposited'in a proper place or receptacle; and

The nature of the invention consists in the novel combination and arrangement of parts, as hereinafter set forth and claimed.

A is the stand or case inclosing the whole apparatus.

B is the seat-opening. l

C, the pail or receptacle within a movable seat, and can be removed at will through the door D.

E, a hopper to contain dry earth, access being had by raising the cover F.

G is a sliding platform, movingr under the hopper E on` guide H. back and forth by means of connections, I and J, extending below guide H to a pin, K.

L is a valve, hung in balance under the platform G, this platform having a circular` opening,`cr, through which the earth passes from the hopper E to valve L.l M is a spring, extending from the front of case A to rear of valve L.

N, a movable seat, (quadrant shape,) hinged to case A, supported at its outer corner by the foot O.

This sliding platform is lnade to move by moving the earth from side to side of the hopperl with anyl suitable instrument.

a" and b' areth'e points of connection between the platform 'G and the guide H.

P is a slot or recessto receive the foot.0 when the closet is closed.

The operation of my inveut'ou is as follows: The position of parts shown by dotted lines in fig. 3 is that in which they are generally placed. for use.

When the lseat N is `,withdrawn for use, the bottom of hopper E being open, a portion of earth passing from E through a into valve L, after. use, the excrement being deposited in the receptacle C, the seat N' is replaced within the case A. 'lhe platform (;r,-tal-:'A

ing an inward motion, brings the solid portion of platform G under (directly) the hopperE, and cutsoif the supply of earth. The spring M releasing the rear .end of valve L, the seat-opening B having come immediatel y under the valve L, the earth is, of its own weight, dumped into receptaclcU, covering the deposit of excrement. v

A modification of my invention can be made so as to conduct the urine into the receptacle C, by placing a piece of any suitable metal, so curved'as to accommodate it to the configuration ofthe seat N, immediately under the top of said seat and in front of receptacle C.

Another modification of my invention may be made by making the front of case A solid,l (dispensing with doors,) and hinging the seat N to backv corners of case A, to open from either end instead of from the front.

That I claim as myinvention, and desire to secure by Letters Patent, is-

The combination, of the movable seat N, with the sliding platform G,.valve L, spring M, and hopper E, having the sieve l), wherebyt-he quantity of earth to be used, and the time of passage is regulated, arranged to operate in the manner and for the purpose specified. l

GEORGE W. ROBERTS.
